National Pension Estimator
Roughly estimate your National Pension from contribution years and average income (2026 basis).
2026 basis (A-value 3,193,511, replacement 43%), rough estimate. Confirm at the NPS.
How the pension is set
The National Pension reflects both the overall average income (A-value) and your own average income, and grows with contribution years. For 2026 the A-value is 3,193,511 won and the replacement rate is 43% (for a 40-year career). This tool uses those to make a rough estimate.
This is a rough estimate
- Actual benefits depend on year-specific constants, revaluation of past income, and exact contribution months.
- This tool shows only a simplified 2026-basis estimate.
- For an accurate figure, check the NPS 'My Pension' service.
Good to know
- You need at least 10 years (120 months) of contributions to receive the old-age pension.
- Longer contributions and higher income mean a larger pension.
- Early claiming reduces it and deferral increases it (not reflected here).
